GAS-GENERATOR.

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed November 21, 1919. Serial No. 339,598.

To all whom it may concern:

Be it known that we, FRED TURNER and new and useful Improvements inGas-Generators, of which the following is a specifi cation. I

This invention relates to acetylene-gas generators, and embodies amongother features an auxiliary carbid container. adapted for use when it isnecessary to refill the main carbid container, thus maintaining thedevice in operation while performing this duty.

To this end, use is made of an adjustable cover for the water container,the cover supporting an auxiliary carbid container in a position to besubmersed when the cover is tight upon said container, the cover beingprovided with a gas escape opening at WlllCh point the gas is ignitedwhile the main. carbid container is being refilled. I

Other objects and advantages will appear when the following detaildescription is taken in connection with the accompanying drawings theinvention residing in the construction, combination and arrangement ofparts as claimed.

In the drawing forming part of this specification like numerals ofreference, indicate similar parts in the several views and whereinFigure 1 is a vertical sectional view through the device forming thesubject matter of our invention.

Fig. 2 is a similar view showing the carbid arranged within the carbidcontainer.

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1.

The device forming the subject matter of our invention comprises a watercontainer 10 and a main carbid container 11, the latter being separatedfrom the water container by means of a partition 12. The partition 12has a small opening 13'from which depends a tube 14, the latterconveying water from the container to the carbid container 11. A similartube 15 is supported by the water container and a valve rod 16 is passedthrough said tube to control the amount of water admitted to the carbidcontainer 11. Projectin from the carbid container is a burner tube 17,which is threaded to accommodate a cap 18. The cap is provided with acentral opening 19 for the escape of gas,

an'dxat which point the gas'isignited. A partition 20 is arranged in thetube 17 to prevent thefiltering element 21 from gaining access to thecarbid container, the partitlon 20 being perforated as shown to allowfor the passage of gas through the openmg 19.- The filtering element ormedium 21 may be of any suitable material as it is provlded to preventthe dust from the carbid or other foreign matter from clogging theopening 19 of the cap. The water container 10 is closed at its upper endby means of a cap 22, while the carbid container is closed at the bottomby means of a cap 23, gaskets 241 being arranged within each cap asshown.

With a view of maintaining the device in operation, when it is necessaryto refill the carbid container 11, we make use of an auxiliary carbidcontainer 25. This container is in the form of a tube depending from thecap 22. The tube 25 is open at the bottom and supports the stopper 26the latter having a vertical bore .to receive a tube 27 A valveincluding a stem 28 is fitted within the tube 27. The cap 22 is providedwith an opening 29 which allows the escape of the generated gas from thecontainer 25, and at which point the gas is ignited. The cap 22 isfurther provided with a vent 30 to admit air to the water chamber. Inpractice, when it is desired to refill the main carbid container 11, andat the same time maintain the device in operation, the cap 22, which isthreadedly associated with the container 10 is removed, and the stopper26 separated from the container 25. A quantity of carbid is then placedin the container 25, and the cap 22 again placed in position.Consequently a quantity of gas is generated in the container 25, whichgas escapes through the opening 29 at which point it is ignited. Theflame is of course extinguished at the point 19 while the container 11is being refilled with carbid.

While it is believed that from the foregoing description, the nature andadvantages of the invention will be readily understood, we desire tohave it understood that we do not limit ourselves to the details ofconstruction, and that such changes may be resorted to when desired asfall within the scope of what is claimed.

Having thus described our invention what we claim as new is 1. Anacetylene gas generator comprising a water container, a carbidcontainer, means for controlling the admittance of water from the watercontainer to the carbid container, said carbid container having a gasoutlet opening, a cap for said water container, an auxiliary carbidcontainer carried by the cap and depending therefrom so that the carbidcontained therein may be submersed, said auxiliary carbid containerbeing open at its lower end, a stopper positioned within said lower end,said cap having an outlet opening for the auxiliary carbid container,and a valve arranged in said stopper between the water container andsaid auxiliary carbid container.

2. An acetylene gas generator comprising a water container, a carbidcontainer, means for controlling the admittance of water from the watercontainer to the carbid container, said carbid container having a gasoutlet opening, a cap for said water container, an auxiliary carbidcontainer carried by the cap and depending therefrom and adapted to bepartly submersed, said cap having an outlet opening for the auxiliarycarbid container, a stopper fitted within the auxiliary container andthe auxiliary carbid container, and a valve including a stem arrangedwithin said valve.

In testimony whereof We affix our signatures.

FRED TURNER. THOMAS BURTON.
